Erosion occurs when the soil breaks because of strong water discharge during heavy storm. Wind is also a primary cause of erosion when it blows hard enough on unprotected so…il to lift and move it away. Ocean waves, river currents, and glacial movement also erode large amounts of rock and soil. Actually, the erosion occurs because of the impact of the fluid particles on to the surface of the solid materials which are subject to this fluid flow, and in a fluid flow the amount of fluid volume per time unit. For example, L/S (Litre per second) defines the speed of the fluid element impacts. The power of this impact will increase if the direction of flow is more perpendicular to the surface. However, the amount of erosion also depends on the inherent forces between molecules of materials which are subject to fluid flow. As an example, in an elbow in a piping element, where the vector direction of the flow changes, there are more impacts and then more erosion occurs. In this situation, if we increase the flow speed, the erosion rate will increase.

Foot path erosion occurs when an excessive number of people walk on a path, usually most common at national parks. it could also happen when a considerable amount of people wa…lk on a grass area, the grass eventually dies and a path is formed. Hope this helps.

Erosion occurs when strong winds blow removing the top fertile layer of soil. The top soil containing clay,loam and organic matter is carried away by strong winds to many kil…ometers and deposited elsewhere forming fertile surface soil especially in Europe and North America, where productive farming has developed.Dunes, formed by mounds of sand, move by strong winds burying oases and ancient cities.Sedimentation crusts are degraded on the surface of stripped soils, weathering the rocks with abrasion at their base where they are in contact with the soil.Sheets of sand traveling close to the ground degrades crops in semi-arid zones.Wind erosion reduces the nutrients and water in soil, making the environment drier.Only large rocks are left when the lose soil is slowly shifted afar by the wind.

Weathering breaks materialn down and erosion transports that broken down material. As an example, weathering breaks a mountain down into smaller rocks, and those smaller r…ocks can be transported by streams (erosion), but the streams cannot simply move the whole mountain.
